The structural origin of enhanced piezoelectric performance and stability in KNN-based ceramics can be attributed to the hierarchical nanodomain architecture with phase coexistence.
Owing to growing environmental concerns, the development of lead-free piezoelectrics with comparable performance benchmark Pb(Zr,Ti)O3 (PZT) becomes great urgency. However, a further enhancement based on existing strategies has reached bottleneck. Here we achieve slush polar state multiphase coexistence in potassium-sodium niobate (KNN) piezoceramics, which shows novel relaxor behavior, i.e., frequency dispersion at transition between different ferroelectric phases. It is very from...
The p53 tumor suppressor is a potent transcription factor that plays key role in the regulation of cellular responses to stress. It controlled by its negative regulator MDM2, which binds directly and inhibits transcriptional activity. MDM2 also targets for degradation proteasome. Many tumors produce high levels thereby impairing function. Restoration activity inhibiting p53-MDM2 interaction may represent novel approach cancer treatment. RG7112 (2g) first clinical small-molecule inhibitor...
With growing concern over world environmental problems and increasing legislative restriction on using lead lead-containing materials, a feasible replacement for lead-based piezoceramics is desperately needed.

Moreover, excellent stability also observed from room to 170 (430 at 100 370 °C). Thermally stimulated...
Due to growing environmental concerns on the toxicity of lead-based piezoelectric materials, lead-free alternatives are urgently required but so far have not been able reach competitive performance.

We achieve an ultrahigh constant ( d33) 700 ± 30 pC/N BaTiO3-based ceramics, maintaining >600 over...
